WARNING
Dangerous potentials exist between chassis and ground.
Exercise extreme caution.
NOTE
Due to interaction of range adjustments, adjustment of one
range will require checking and, if necessary, readjustment of
other ranges.
(1) Set TI voltage dials to 10.000000.
(2) Adjust R9, CAL 10V (fig. 5 or 6) for a null indication on null detector (R).
(3) Perform (1) and (2) above but do not report adjustment.
(4) Set TI voltage dials to 100.00000.
(5) Adjust R5, CAL 100V (fig. 5 or 6) for a null indication on null detector (R).
(6) Perform (4) and (5) above but do not report adjustment.
(7) Set TI voltage dials to 1000.0000.
(8) Adjust R1, CAL 1000V (fig. 5 or 6) for a null indication on null detector (R).
20. Panel Meter (Voltage)
a. Performance Check
(1) Disconnect TI from equipment setup.
(2) Set VOLTAGE RANGE switch to POWER switch to OPR.
(3) Adjust voltage dials for indication of 1.0 on 0-to-1.0 scale of panel meter.
(4) If voltage dials do not indicate between 9.700000 and 10.300000, perform b
below.
(5) Set POWER switch to STDBY/RESET.
b. Adjustments
